Python Robot Programming 101: Master Python Coding for Robotics

Python has risen to become one of the most popular programming languages for robotics, among both newer robot users and those looking for advanced functionality. In this guide, we explain all you need to know to get started with Python coding for robotics.

While not traditionally considered a “robot programming language, ” Python has grown in popularity among roboticists in the last couple of decades thanks to its versatility, simplicity, and interoperability.

At RoboDK, our powerful and popular Python API adds an almost limitless level of possibility to robot programming.

Whether you are just starting in robotics or an experienced user looking to incorporate advanced features, this guide will introduce you to the essentials of Python robot programming.

Why Choose Python for Robot Programming?

There was a time when programming robots with Python would have been seen as a joke. By industrial engineers, it was considered a language that wasn’t for “serious robotics applications.”

Those days have passed…

In industrial robotics, programming languages were traditionally manufacturer-specific. Each robot brand still has its own proprietary programming language, often with conflicting and complicated programming conventions.

But, with the rise of easy-to-use robotic systems, Python has moved from hobby and research applications firmly into industrial robotics. With its beginner-friendly nature and powerful capabilities, the language is sometimes known as “The Swiss Army Knife” of programming.

Compared to the old manufacturer-specific robot programming languages, Python is universal, flexible, and extensively documented. Anyone can pick it up and start building robot cells with advanced capabilities.

If you want to spend less time programming and more time creating robot applications, Python could be the programming language for you.

How to Get Started with Python and RoboDK

RoboDK is a powerful tool for robot simulation and offline programming. Its graphical interface allows you to create robot programs without having to type a single line of code. However, when you combine RoboDK with Python through the API or scripts, you can access an impressive level of functionality.

Here are 3 steps you can take to get started with Python and RoboDK:

Step 1: Set Up Your Python Environment

First, install both RoboDK and Python on your computer. [This tutorial in the RoboDK documentation][RKDOCINSTALL] shows the process for installing RoboDK and this page on the Python website lists the latest release.

From here, install the RoboDK Python API as explained in this tutorial in the documentation.

Step 2: Get Familiar with RoboDK API

Once installed, become familiar with the Python API and what it can do.

Some useful places to start include:

  • Tutorials in the documentation These steps guide you through the basics of setting up a RoboDK Python project.
  • This Video Tutorial This video tutorial on our YouTube Channel guides you through using Python for a simulated welding operation.
  • The RoboDK Example Folder — The examples shipped with RoboDK (which are accessible in the RoboDK directory on your computer) include various robot stations programmed in Python. These examples can be a good place to learn how to structure and create Python robot programs.

Step 3: Write and Test Your First Python Robot Script

Once you are a little familiar with Python programming in RoboDK, it’s helpful to build a simple application using what you have learned.

Depending on your level of experience and programming goals, you could either start by creating a simple Python script within RoboDK or link your external code to RoboDK through the API.

Testing is a key step. Frequently test the changes you make to your Python code by running them in the RoboDK simulator. This allows you to see how the robot will move in the real world.

3 Advanced Techniques to Elevate Your Python Robot Project

The real power of combining of RoboDK and Python comes with advanced capabilities it can add to your robot.

Here are 3 ways that can elevate your python program’s capabilities:

Automating Repetitive Tasks

One powerful capability of RoboDK’s Python API is its ability to automate repetitive tasks. There are endless possibilities, from batch creating motion trajectories, passing program parameters, and monitoring robot performance in real time.

For more information, read our article Introduction to RoboDK’s API: How to Automate Repetitive Tasks.

Integrating Machine Learning

Machine learning and artificial intelligence are traditionally complex aspect of programming. However, a significant benefit of Python is the huge number of freely available software libraries for advanced machine learning. With the RoboDK API, you can easily add this functionality to your robot projects.
